Imagine you're going about your day, minding your own business, when all of a sudden, out of nowhere, there's a goat! That's the premise of the goat prank that's become a tradition in Spokane, Washington. The link includes a video of a Spokane anchorwoman who keeps repeating excitedly, "I've been goated! I've been goated!":

Spokane community members have the opportunity to play a great practical joke by having a real baby goat delivered to offices or meetings. A $50 donation to Wishing Star will send a goat to an unsuspecting friend or co-worker on the day of choice. The recipient will be asked to make a donation to Wishing Star to pay for the removal of the goat. Last year Wishing Star was able to raise over $20,000 through 'goating,' with five to six goats traveling to offices throughout Spokane each day.
